Abstract :
This paper treats the study of on-chip temperature compensation of a broad-band UHF VCO. Analysis, design and evaluation of IC oscillators are described. Excellent agreement between simulation and measurement is demonstrated. The frequency deviation drift specification over a 25/spl deg/C temperature range has been reduced to <0.5 MHz within the frequency range of 470/spl sim/930 MHz.
